I just watched through the depecialized trilogy last week.

It goes a lot further than restore and "unedited". As an example, the 4th episode (first movie) received a ton of enhancements. They used sources ranging from the laser disc edition to photos. The result is something that looks absolutely beautiful and very comfortable to watch on a modern display.

I think it's a lot closer to what we expected the "special editions" to be.

As a side note... I used the "Machete order" when watching the movies. Made me appreciate Episode 2 and 3 a lot more than I had previously. I quite enjoyed them in the context the order creates.
